'srncIFIoATIoN forming part of Letters Patent No. 638,198, datedNovember as, 1899. Application filed January 30, 1899. Serial No.703,779. (No model.)

To all whom it may concern.-

Be it known that I, JOHN W. HILE, of Kansas City, Wyandotte county,Kansas, have invented certain new and useful Improvements inGasolene-Lamps, of which the following is a specification.

My invention relates to gasolene-lamps; and my object is to provide agasolene-lamp wherein the vapor discharge maybe controlled and regulatedby so locating the valve that it intercepts the vapor-passage instead ofthe oilpassage, as is customary.

A further object is to provide a swivel connection for the mixing tubeor tubes which carry the lamps in order that the relation between thelatter and the generator may be varied, and thus render access to eitherfor cleaning or any other purpose more convenient than where therelation between such parts is fixed.

A still further object is to provide a lamp construction wherein thesupply-tank may be readily and easily removed from position forrecharging without lifting the lamp down from the hook or other pointfrom which it is suspended.

Other objects will hereinafter appear and be pointed out in the appendedclaims, and in order that the invention may be fully understoodreference is to be had to the accompanying drawings, in WhlCl1' Figure 1represents a side view of a gasolene suspension lamp with a plurality ofburners embodying my invention. Fig. 2 is a section taken on the line IIII of Fig. 1. Fig. 3 is an enlarged detailed view, partly in section,showing the connection between the tank and the suspension-rod. Fig. 4is a horizontal section of the generator of each burner. Fig. 5 is asection showing the tapering passage of the discharge-nozzle. Fig. 6 isan enlarged section taken on the line VI VI of Fig. 1. Fig. 7 is asimilar view of a modified form of construction. Fig. 8 is a side viewof my lamp as constructed with a single burner. Fig. 9 is an enlargedsection taken on the line IX IX of Fig. 8. Fig. 10 represents a detailperspective view showing the structure as adapted to be hung upon awall. Fig. 11 is a similar view of a slightly-modified construction.Fig. 12 shows a modified form of mixing-tube.

In said drawings, 1 designates a vertical tubular rod surmounted by aT'coupling 2, and secured to said coupling is a bent rod 3, the upperend of said rod being about vertically over'rod 1 and provided with aneye or loop l for engagement with a pendent hook 5, secured to theceiling or equivalent part of a room. 6 designates a tube secured tosaid coupling and having its upper end arranged vertically and offlaring or inverted conical form to receive the tapered lower end of adischarge-pipe 7, depending vertically from the gasolene-tank 8, saidtank being provided with the customary screw-cap 8, which must beremoved when the tank is to be recharged. The said pipe 7. is providedwith a valve 9 of the usual or any preferred construction,which valve isalways open when the tank is seated in the flaring tube 6. When thetankis to be recharged, said valve is first closed, then the tankremoved by simply lifting it vertically upward until the tapered lowerend of pipe 7 is disengaged from said flared tube, there beingsufficient space between the top of the tank and the upper end of rod 3to permit this operation. Thus it will be seen that the tank can beeasily removed when desired without lifting the lamp down from thesupporting-hook.

In Fig. 8, representing the single-burner type of lamp, the tube 6corresponding to the tube (Sand having the same flaring upper end, is ofsegmental form below such end and is secured to the T-coupling, and inthis connection it will furthermore be noticed that rod 3, correspondingto rod 3, is bent only at its upper end, so as to bring the eye or loop4 vertically over the center of the tank.

In Fig. 10 in lieu of the rod 3 or 3 the vertical bar 3 is employed,said bar being provided at its upper end with an upwardly-tapering slot3, the wide or lower end of said slot being of sufficient size to slipover the head of bolt 3 driven into the wall or equivalent part of aroom, the bar being then lowered until the narrow end of the slotembraces the bolt, it will be seen that an accidental disengagement ofthe bar and bolt cannot take place, but that the bar can be easily andquickly removed by simply raising it until the large end of the slotcomes opposite the head of the bolt and then moving it forward until itsdisengagement is complete. In Fig. 11 the construction is the same,except a different style of coupling 2 is substituted in place ofcoupling 2, and the pipe 6 is of a slightly-different configuration.

1O designates a four-way coupling uniting the supply-pipe 1 with thevertical pendent rod 11 and the laterally-projecting branch pipe 12,said branch pipes being in communication with the pipe 1. Mounted uponthe outer end of each branch pipe is a cast-metal generator, the sameconsisting of a tubular arm 13 in longitudinal alinement with pipe 12and provided with a narrow vapor-passage 14, a packing-box 15, and aneedle-Valve 16, the latter being arranged to control the passage ofvapor from the passage 14 to the passage of the tubular angle-pipe 17,provided with a discharge-nozzle in the form of a screwplug 18, saidplug being provided with a tapering passage 19, terminating in anexceedingly fine jet-orifice in order that the vapor will be dischargedtherefrom under considerable pressure. The arms 13 and 17 of the castingare united by the cross-bar 20 for the purpose of adding strength to thegenerator and for another purpose, which will be hereinafter explained.

20 designates an inverted approximately U-shaped bracket secured uponthe lower end of rod 11 in any suitable manner, the lower ends of saidbracket being formed or provided with outwardly-projecting arms 21,terminating in curved spring-arms 22, the ends of the arms 22 beingsecured by clamping-bolts 23 to arms 21.

24 designates the approximately se micircular mixing-tubes,which areswiveled in clampopposite and in longitudinal alinement with thedischarge-nozzle plugs 18, and the lamp is vertically below the body ofthe generator, said tube and lamp being held reliably in this positionby the pressure of the arm 22, the friction between the tube 24 and saidarm being sufficient to prevent any accidental rotary movement of thetube.

WVhen it is desired to clean either the generator or the lamp, the tubeis swung around between the clamp-arms and the lamp thereby withdrawnfrom under the generator. This action is necessary when it is desired toremove the globe from the lamp, as the latter is normally so close tothe generator that it would be impossible to remove it without firstswinging it out of the way.

In Fig. 7 the arm of the bracket 20 is shown as split centrally andterminating in the semicircular arms 21 adapted to clasp the mixing-tube, and united, as in Figs. 1 and 6, by the clamping-bolt 23.

In the single-burner lamp shown at Fig. 8 the three-way coupling 10 isemployed, and projecting forward therefrom is a single branch arm 12,carrying the generator at its outer end. The rod 11, depending from thecoupling, terminates in a threaded stem 11*, and mounted upon said rodis an arm 21*, secured rigidly to the mixing-tube 24 in any suitable orpreferred manner and held in position by means of the clamping-nut 23engaging the lower end of the stem. hen it is desired to Withdraw thelamp carried by this tube 24 from under the generator, the tube is swungto the desired position,- the stem 11 forming the axis of such movement,as indicated in Fig. 9.

In Fig. 12 I show a mixing-tube of sectional construction, consisting ofthe upper or stationary portion 24" and the lower or swiveled portion 24the former being seated at its lower end in the vertical collar 20formed or secured at the outer end of the bracket carried by rod 11, orin case the lamp is of the single-burner variety the collar 20 may beformed or secured at the outer end of the arm 21 and screwed upon thelower end of said collar is a packing-box 20 in which the upper end ofthe lower member 24 of the mixing-tube is journaled, said lower memberbeing supported in said box by means of its angular enlargement orcollar 24, a packingring 20, seated in said box,serving the purpose ofmaking this swivel-joint perfectly airtight and at the same timepressing against the collar 24 with sufficient force to prevent theaccidental swivel operation of the lower member, the latter carrying theburner at its lower end, as described with respect to the mixing-tube24. By this construction it is obvious that the lamp may be swung fromunder the generator when it is desired to start the generation of vaporand then may be ignited before it is repositioned under the generatorbecause of the continuous passage from the mouth of the mixing-tube tothe lamp.

To ignite the lamp in either case, it being assumed that the parts arein the relative positions shown in Figs. 1 and 8, it is first necessaryto swing the lamp from under the generator and hold a lighted taper ortorch below the latter for a short time in order to raise the generatorto the temperature required to transform the oil in the passage toVapor. The lampis then swung to operative position below the generatorand clamped rig idly in such position, if desired, by turning the bolt23 or nut 23, as the case may be. The valve 16 is now opened to permitthe vapor thus generated to pass in the direction indicated by thearrow, Fig. 4, and be forcibly ejected through the jet-orifice of thedischargenozzle plug, this forcible discharge of vapor into the inletend of the mixing-tube 24 drawing with it into said tube a sufficientvolume of air to form a combustible gas, which passes up into the lampand is there ignited. The heat from the lamp impinges upon the body ofthe generator, as hereinbefore explained, and consequently serves tomaintain the latter at a sufficiently high temperature to vaporize theoil as fast as it enters passage 14. It will be noticed in thisconnection that the cross-bar 20 of the generator is in the direct pathof the heat emanating from the lamp and being a goodincidentally theflame instead of regulating.

simply the quantity of oil to be vaporized. In the latter case, Wherethe oil-flow is con trolled by the valve, it is impossible to regulatethe size of the flame to the same degree that it can be regulated wherethe valve in tercepts the passage of the vapor. To extinguish the lamp,it is only necessary to close the vapor-passage 14 by the propermanipulation of valve 16.

The tank of course may be more remotely situated than the point at whichit is illus trated, if desired, the connecting-pipe of course being ofcorrespondingly-increased length.

From the above description it will be apparent that I have produced agasolene-lamp which is subject to variation in its structural featureswithout departing from the spirit and scope of my invention orsacrificing any of its advantages.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a gasolene-lamp, a supporting-rod, a

generator, a mixing-tube, having its inlet end arranged to receive thevapor from the generator, and carrying a burner at its lower end; saidmixing-tube bearing such a relation to the supporting-rod that it may beswung to a position where its burner is vertically below said generator,and means for securing the mixing-tube in a rigid relation to thegenerator, substantially as described.

2. In a gasolene-lamp, a generator, a mixing-tube support provided witha collar, a packing-box secured upon one end of the collar, and amixing-tube, comprising two sections, one secured rigidly in theunobstructed end of the collar and having its receiving end opposite thedischarge end of the generator; the other member being swiveled in saidpack ing-box with one end registering with the upper member and carryinga burner at its opposite end, substantially as described.

3. In a gasolene-lamp, the combination ofa supply-pipe 1, a branch pipe2, a mixingtube having its inlet end adjacent to the upper end of thebranch pipe, and carrying a burner at its opposite end, and a generatorvertically over the burner and secured upon the outer end of the branchpipe with its discharge end opposite the mouth or inlet end of themixing-tube, said generator consisting of the upper portion 13, havingan oil-passage 14: communicating with the branch pipe, and an angular orL-shaped vapor-passage communicating at one end with the outer end ofthe oil-passage and arranged to discharge the vapor from its oppositeend into the mixingtube, and a needle-valve in the body portion of thegenerator and controlling the same at the junction of the oil-passageand said angular or L-shaped passage, substantially as described.

111 testimony whereof I affix my signature in the presence of twoWitnesses.
